DEVICE FOR CLEANING CAPSULES.

Specification of Letters Patent.

Patented Dec. 26, 1905.

Application filed August 28, 1905. Serial No. 276,048.

To (tZZ whom it may concern:

Be it known that I, OTTO EDWARD MUED LER, of Louisville, in the county of J eiferson and State of Kentucky, have invented certain new and useful Improvements in Devices for Cleaning Capsules; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which- 7113 appertains to make and use the same.

My lnvention relates to an improvement in a device for cleaning capsules, the object of the invention being to provide a closed structure with two compartments separated by a sieve and containing sand, sugar, or other suitable material, which when shaken passes through the meshes of the sieve and into contact with the capsules on the sieve, thereby removing by attrition any particles adhering to the outer surface of the capsules.

IVith this end in view my invention consists in the details of construction, which will be more fully described and pointed out in the following specification and claim.

In the accompanying drawings, Figure 1 is a view in perspective, showing the drawer with a sieve-bottom partly open. Fig. 2 is a view in longitudinal section of the same, showing the drawer closed; and Fig. 3 is a view in transverse section.

1 represents a rectangular box or casing provided at one end near its top with an opening 2 to receive the drawer 3. This drawer is provided at its front with the knob or pull 4 and is as long and wide as the internal dimensions of the box or casing 1. The bottom 5 of this box or casing is preferably of sieve form, the openings being sufficiently large to permit of the free and unrestricted passage of the sand or sugar grains used in the process, but not large enough to permit of the passage of the smaller-sized capsules. The drawer thus formed and provided with a reticulated bottom is supported within the box or casing, with the tops of its sides and ends in close contact with the under side of the top of said box or casing, by the ribs 6, secured to or integral with the sides of the box, thus leaving considerable space 7 between the bottom of the drawer and the bottom of the box or casing.

In the operation of my device the capsules are placed on the bottom of the drawer and the drawer fully closed. By now taking the box in the hands and shaking it more or less the sand, sugar, or other material located within the compartment 7 of the box passes through the reticulated bottom of the drawer into intimate contact with the capsules and removes therefrom by attrition all matter adhering to the outer surfaces of the capsules. As soon as the box comes to a rest all the cleaning material employed gravitates through the open-work bottom of the drawer to the compartment below. By this method a large number of capsules can be quickly and thoroughly cleaned.

Having fully described my invention,what I claim as new, and desire to secure by Letters Patent, is

As a new article of manufacture, a box having an opening at one end only, the said opening being located near the top of said box and extending the width thereof, and a drawer located in said opening, the said drawer having a reticulated bottom to permit the material contained in the lower compartment of the box to pass through the bottom of the drawer, and into contact with the articles in said drawer.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

OTTO EDWARD MUELLER.
